Choke Coil Toroidal Ferrite Core Permanent Type Better Performance

Choke Coil Toroidal Ferrite Core

Toroidal core features:

1.Maximum operating temperature: 150 degrees Celsius

2.Coated with epoxy resin: 500 VAC

3.Toroidal shape provides good magnetic flux coupling and low stray flux leakage

4.Toroidal shape is the height (also referred as thickness) is easy to vary and requires no tooling changes

Introductions & Advantages

1.Toroid cores are the core type geometry of choice for optimizing performance. A toroid of round cross-section offers better performance than one of rectangular cross-section.

2. The symmetry of T cores circular geometry minimizes the amount of external magnetic flux produced. T cores produce much lower amounts of unwanted electromagnetic interference. 

3. Toroidal coil has a lot of surface area from which it can dissipate heat hence it cools much better than other core types.  Cooler windings result in higher efficiency and may allow more utilization of the core's capability.

4. Because of its circular nature, the magnetic path of a T-core is an unbroken continuous path unless intentionally broken. 

5.There is no air gap in the magnetic path (unless intentionally added) hence optimal use can be made of high permeability materials.

6.The core material is sensitive to stresses produced by the winding processes. 

Applications of T-core

1.T cores are widely applied in Power, Current transformer and Telecom field.

2.T-core used in power: power transformer core, power inductor core, DC-DC Converters, DC converter core, Compact Power Transformer, Small and Low Profile Power Inductors, Wideband transformers, and other inductive delay lines.

3.T-core used in telecom: xDSL pass-band Filters, Spilters, EMI Inductors, and Filter Inductors with Tight Tolerance.
4.T-core used in current transformer: EMI-suppression in power lines, EMI-suppression in mains filters.
